:iursovsn INVALID-BEDSTBAD.

To ALL WHoM rr' MAY concerts;

ARe it known that DLLAVAN D. MsRSHflatc of Croydon, in the county oi' Sullivan, and State of New Hampshire, deceasedin` his lifetime invented a new and improved device for raising and relieving sick and other disabled personsfrom-a recumbent position in hed, and removing them from one bed to another, or to a chair-,or otherplbce of rest or repose.; and that the following' is a. full and exa-ct'description thereof, reference being had to thc accompanying drawings, and to the letters of reference marked thereon, (the same letters rep'- resenting corresponding parts in-the diil'erent igures,) making a part of this specification.

The nature of the invention of said MARSH consists inv providing suitable mechanism attached to the hoor o r platform, onwhicli the bedstead may be rmly sccured,l,nnd against which the mechanism rests, by-which a v 4sich person, orone disabled, by wounds,.or otherwise, maybe raised either at the head or feet, or on either side,

to any position desired, orremoved'from'onc bedito another, when desired.

To enable others skilled'iri the art to ineke and use the invention of thesaid MARSH, its constructionand operation are described as follows, namely:

X is the door or `platform to which said inechsnism is fastened, by means of the bed-piece and th'e screws VV. The bedstead Y, though not attached, is firmlyconirie'd in place onythe door by means of the bed-ipiece U; and also the bed-piece, U', fastened tothe door by the screws V V'.

A A aretwvo upright'supoorting-bars united atthe topA bythe cross-'bar B, the upper surface of which "forms a circular bed-plate, s seen in Figure 4, on which the circular plate Fz rests and revolves. Frictionballs or rollers'may be used between the faces of these two plates, to render their `motion casier. B' is also a. cross-bar or brace, uniting the supportingfbars A A'. d

C is the king-bolt, which passes through the cross-bars B B', and the apertures b b' b" in the supporting-- lever D, the latter being strengthened by the steel plate H, which passes over the upper surface of the saine, and laps over each end, and is fastened to the supporting-lever by 'screws or nails.

E E' E" are supporting-arms, made if-steel, of sufficient -size and strength to bear the Weight of the patient, which pass over through slots to the supporting-lever D, as seen more fullyn Figure 2, and having a. sliding motion in said slots. i Y F F', ve., are pulleys at`the ends ofthe supporting-arms, over which the cordsZ Z', Xue., 'and J J, 8m., pass, the said cords being fastened to thesockets d d', vc., at the ends ot the restngfbars g g g", the ends of the latter reposing in said sockets. y

G G G", one of which is shown in FiguroiQ, are double guide-pulleys in the pulley-frame I, over which the cords Z', Sie., and J J', dto., nass. Separatepulleys maybe used for each cord, if' necessary, in the actual opera-tion' of the machine. vThe cords Z, Z", 51e., designated on'thedrawings by dark lines, aroused for elevati ing or depressing the head or feet of the patien t, or lifting and, removing him from one bed to another, or to a. f

chair or other place of rest, as muy be desired, and nre fastened to the ends ofthe sockets d nl', c.,and thence pass over tho pulleys F F, Svc., the guide-pulleys G G' G", and thence down, and -are'conned to the axles of -the ratchehnfheels K K' K", which are operated bythe cranks L L L", the said cranks and ratchet-wheels beingnore fully represented in Figure 5. i y

The cords JJ', he., designated by red lines, are designed for lifting the patient on either side, and are` also confined to' the sockets d d', Etc., and thence pass overthe pulleys F F', site., the guide-pulleys-G, and

thence down, and are confined to the aides a e', the cord J to the axle a, and the co'rdJ' to the axle c', operated` by the crank It, as seen in Figure 7. The corclsJ J', &c., are united at the points it', 86o., thence eachv form-- ing a single cord down the axles a a', by which device eitherside, of the patient is lifted equally. i If it is dcsiredto raise the left side, the crank R is 'turned from you if the right side, thesame crankfis'turned towards you. The crank is kept from turning back either way, ns the unitedcords, J J', may be respectively operated by the pin z, as seen in Figure 1. -N
